How Golgi residents remain in their designated compartments despite a constant flow of secretory cargo is incompletely understood. Here, we determine the structure of the COPI vesicle coat containing GOLPH3, an adaptor protein that binds the cytosolic tails of many Golgi residents. Analysis of this structure, together with structure-guided mutagenesis and functional assays, reveals how GOLPH3 uses coincidence detection of COPI and lipids to engage Golgi residents preferentially at late cisternae. Our findings rationalize the logic of cisternal maturation and explain how COPI can engage different types of substrates in different Golgi cisternae to retrieve some proteins back to the ER while retaining others within the Golgi apparatus. | ||||||||||||||||||

The center of each coated vesicle or bud was picked and radii were assigned using a custom-written plugin (https://www.biochem.mpg.de/7940000/Pick-Particle). Initial coordinates for subsequent particle search were seeded with an even spacing of 10.9 nm (8 pixels in tomograms binned 8 times) perpendicular to the sphere surface, and with random in-plane rotation, yielding a total of 193104 particles (C3).
